CYLINDER-LUBRICATQR.

SPECIFICATION forming part of Letters Patent No. 400,653, dated April 2,1889.

Application led May 22, 1888. Serial No. 274,747. (No model.)

` citizen of the United States, and a resident of the city ofCincinnati, in the county of Hamilton and State of Ohio, have inventedcertain new and useful Improvementsin Oylinder- Lubricators, of whichthe following is a speciication.

The several features of my invention and the advantages arising fromtheir use conjointly or otherwise will be apparent from the followingdescription.

In the accompanying drawings, forming part of this specification, Figurelis a central section of one end of a cylinder, showing my device inconnection with the pist-on. Fig. 2 is an end elevation of the same,viewed from that end which is at the left-hand side in Fig. l.

The device is intended for use more particularly with the longhorizontal Water-cylinders commonly employed with hydraulic elevators.

A represents the cylinder, B the regular piston, and C the piston-rodoperated by the same. The stem D is screwed into the piston-rod O. rPhepulley E, preferably provided with a V-groove and having a sleeve-hub,e, is centered on the stem D. .The end of the sleeve e rests against thenut C', and in this way holds the pulley in place. The diaphragm orauxiliary piston F is centered on the sleeve e. It is provided at itsouter edge with a suitable packing device, preferably such as shown thatis, a ring, f, resting on alange, f, forining a space, f2, to be filledwith compressible packing material.

The space between the pistons B and F is designated by the letter G.Vithin the space G, rigidly attached to the sleeve e, is a hub, H,provided with a series of spokes, 72., which project outward toward theface of the cylinder. Over the end of each spoke is slipped a yoke, I,carrying a roller, I and adapted to slide on The rollers I are heldagainst the face of .the cylinder by the springs i, which obtainabearing from the nuts il on the spokes and press directly against theyokes I. The standards J, attached to the piston F, carry the shaft j,on which the grooved pulleys J J 2 are loosely mounted and placed insuch position ,that the cord passing in their grooves can pass directlyinto the groove of the pulley E.

On the cylinder-flange A a grooved pulley, K, is supported by asuit-able standard, 7.o. It is placed in line with the pulley J 2; l Thecord L is attached to a bracket or stop,.a, on the flange A', (or othersuitable stationary object,) in line with pulley J g then passes overthe pulley J 5. thence around the pulleys E and J 2; then out throughthe cylinder, over the pulley K, and then over a pulley or pulleys, S,attached to the ceiling T or other equivalent suitable support. To theend of this cord is attached a weight, W. The space Gis partially filledwith grease or other lubricant, which is introduced through thehand-holes]L13 in the diaphragm F. The diaphragm F is preferablyprovided with a trussbrace, M, attached to the stem. D. The strain ofthe diaphragm is thereby transferred to the stem D, and the sleeve e isrelieved of strain, and the friction between the sleeve and thediaphragm is thereby lessened.

The mode of operation of the device is as follows: Vhen the pistonrecedcs from the open end of the cylinder A', the cord L is drawn intothe cylinder, and as it passes over the V-pulley E imparts a rotarymotion thereto, which motion is transmitted to the spokes h. In this Waythe rollers I are made to continually wipe the face of the cylinder,and, moving as they do in a mass of lubricant, se-

cure an effectual lubrication of the surface.`

In the opposite movement of the piston the cord L is drawn out by theweight W, thus j moving the rollers in the opposite direction.

By these means the surface of the cylinder is kept constantly andthoroughly lubricated.

The use of the diaphragm F is particularly advantageous, as it serves tokeep the lubricant moving through the cylinder and not left at one end,as occurs when the diaphragm is omitted and the lubricant throwndirectlyinto the cylinder.

While the various features of my'invention are preferably employedtogether, one or more of them may be used without the remainder, and inso far as applicable one or more of said features may be used inconnection with cylinders or lubricating devices other than those hereinspecifically described.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination of the cylinder and the IOO.

piston i3, a diaphragm, F, traveling baclmaid and forward in saidcylinder, and a rotating lubricant-distrilinter located in the spacebetween the said piston and said diaphragm, substantially as and for thepurposes specified.

2. The combination of a cylinder, a pistonhead, adiaphragm fixed to thepiston-r0d and traveling therewith and forming a space therewith, and arotating distributer within the said space, and means for operating thesaid distributer, substantially as and for the purposes speciied.

3. The combination of the cylinder A, the piston B, the stein D,diaphragm F, hub H, sleeve e, spokes h, lubricators attached to the endsof the spokes 71, and means for rotating the hub ll, substantially asand for the purposes specified.
